U20 Ultra-Skeleton Tourbillon

An authentic haute horlogerie sculpture, the U20 Ultra-Skeleton Tourbillon is designed in such a way as to provide a 3D view of its flying movement from any angle. Taking the quest for transparency to its ultimate limits, the Angelus showcases a wealth of skills dedicated to optimising each element and preserving only essential elements, while maintaining the rigidity and sturdiness of the entirely open-worked movement. Built on a sapphire main plate, the calibre appears to be literally floating inside the carbon fibre case, which also displays fascinating feats. Fitted with chamfered titanium lugs reflecting the light, it dispenses with a bezel and is instead topped by an imposing sapphire crystal dome that magnificently highlights the overall transparency and the 3D architecture. 18-piece limited edition.
